actl workspace pods run as root by convention, so OpenMPI's root guard aborts every mpirun. Bake OMPI_ALLOW_RUN_AS_ROOT(_CONFIRM)=1 into the actl stage only; base/gromacs stay unchanged since standalone runs use --user and the guard remains meaningful there.

Fixes ENG-128 (https://linear.app/astera/issue/ENG-128).
actl workspace pods run as root by convention, so OpenMPI's root guard aborts every
mpirun(reported by Taylor Womack). This bakesOMPI_ALLOW_RUN_AS_ROOT=1andOMPI_ALLOW_RUN_AS_ROOT_CONFIRM=1into theENVblock ofDockerfile.actl, matching NVIDIA NGC HPC image practice.Deliberately not added to
Dockerfile.base/Dockerfile.gromacs: those portable stages are run standalone withdocker run --user $(id -u), where the root guard stays meaningful.Validated with
docker buildx build --check --build-arg GROMACS_IMAGE=scratch -f Dockerfile.actl .(no warnings), same as CI.
